Fujifilm X-M1 versus Fujifilm X-A3

The Fujifilm X-M1 and the Fujifilm X-A3 are two digital cameras that were revealed to the public, respectively, in June 2013 and August 2016. Both the X-M1 and the X-A3 are mirrorless interchangeable lens cameras that are equipped with an APS-C sensor. The X-M1 has a resolution of 16 megapixel, whereas the X-A3 provides 24 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Fujifilm X-M1 vs Fujifilm X-A3

The side-by-side display below illustrates the physical size and weight of the Fujifilm X-M1 and the Fujifilm X-A3. Three consecutive perspectives from the front, the top, and the back are presented. All size dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the X-M1 – represents 100 percent across all the size and weight measures).

In this particular case, the Fujifilm X-M1 and the Fujifilm X-A3 have exactly the same width and height, and, thus, have identically-sized bodies. However, the X-A3 is slightly heavier (3 percent) than the X-M1. In this context, it is worth noting that neither the X-M1 nor the X-A3 are weather-sealed.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an overview of suitable optics in the Fujinon X Lens Catalog. Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.

Concerning battery life, the X-M1 gets 350 shots out of its NP-W126 battery, while the X-A3 can take 410 images on a single charge of its NP-W126S power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The X-A3 was launched at a markedly lower price (by 43 percent) than the X-M1, which puts it into a different market segment. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Fujifilm X-M1 vs Fujifilm X-A3

The size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixels in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Fujifilm X-M1 and Fujifilm X-A3 sensor measures

With 24MP, the X-A3 offers a higher resolution than the X-M1 (16MP), but the X-A3 has smaller individual pixels (pixel pitch of 3.92μm versus 4.80μm for the X-M1). Yet, the X-A3 is a much more recent model (by 3 years and 2 months) than the X-M1, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the X-M1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

X-M1 versus X-A3 MP

For most cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the X-A3 provides a faster frame rate than the X-M1. It can shoot movie footage at 1080/60p, while the X-M1 is limited to 1080/30p.

 

Feature comparison: Fujifilm X-M1 vs Fujifilm X-A3

Apart from body and sensor, cameras can and do differ across a variety of features. The X-M1 and the X-A3 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. The table below summarizes some of the other core capabilities of the Fujifilm X-M1 and Fujifilm X-A3 in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the X-M1 and the X-A3 are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The X-A3 replaced the earlier Fujifilm X-A2, while the X-M1 does not have a direct predecessor.

Review summary: Fujifilm X-M1 vs Fujifilm X-A3

So what conclusions can be drawn? Which of the two cameras – the Fujifilm X-M1 or the Fujifilm X-A3 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Fujifilm X-M1:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • More heavily discounted: Has been available for much longer (launched in June 2013).


Reasons to prefer the Fujifilm X-A3:

  • More detail: Has more megapixels (24 vs 16MP), which boosts linear resolution by 23%.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Longer lasting: Gets more shots (410 versus 350) out of a single battery charge.
  • More affordable: Was introduced into a lower priced category (43 percent cheaper at launch).
  • More modern: Reflects 3 years and 2 months of technical progress since the X-M1 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the X-A3 is the clear winner of the contest (8 : 2 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.

X-M1 02:08 X-A3

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the X-M1 or the X-A3 handle or perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is where reviews by experts come in.

The review scores listed above should be treated with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
